Area 419 Firearms M-Series 300 PRC Sizing Die w/ Zero Shell Holder

The Area 419 M-Series sizing die is a precision 300 PRC reloading die engineered for rifle reloaders who demand exacting headspace control. Built around Area 419's micrometer-adjustable headspace and shoulder bump system, this die lets the reloader dial in neck tension and shoulder bump to thousandths without shims or spacers, producing consistent round-to-round ammunition for precision rifles chambered in .300 PRC.

The M-Series die features a 1-1/4 inch body that threads into the Area 419 Zero press using the Hybrid or 1-1/4 inch Turret. It is not compatible with 7/8 inch turrets or standard 7/8 inch presses. Inside, the die uses precision ground expander mandrels for concentric neck expansion, full-length neck-to-extractor sizing for reliable feeding and tight chamber fit, and a spring-loaded decapping system that streamlines case preparation. Spring ejection makes case retrieval fast during high-volume reloading sessions.

This 300 PRC die ships complete with a matching Zero shell holder, so it is ready to run on a compatible Zero press out of the box. Like all Area 419 reloading tools, it is machined for repeatable performance, long service life, and the tight tolerances precision shooters expect.
